1. Place the letters in the correct order for DNA replication (a, b, c): ___ a. Daughter strands are formed using complementary base pairing.

b. DNA unwinds

c. The DNA of the daughter strands winds together with its parent strand.
2.Why is DNA replication called “semi-conservative”? ___
3.What enzyme unwinds or unzips the parent strand? ___
4.What enzyme connects the new bases to the old bases in the DNA template? ___
5.___DNA replication results in two DNA molecules,

a. each with two new strands

b. one with two new strands and one with 2 original strands

c. each with two original strands
d. each with one new strand and one original strand

6.___DNA replication is said to be semiconservative because:

a. both RNA and DNA synthesis are involved in the process.

b. part of the telomere is lost during each round of replication.

c. a new double helix contains one old and one new strand.

d. each new strand is complementary, not identical, to its template

answer; the tunica intima also called tunica interna, consists of elastic fibers,connective tissue and smooth muscle cells;

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
